WATER-CRANE Specification of Letters Patent.

Patented Nov. 3, 1908.

To all whom it may concern:

Be it known that we, NORMAN ELIGAH OTTO, of Smith Falls, county ofLanark, in the Province of Ontario, Canada, and ALBERT \VILsON Or'ro, ofOsgoode Station, county of Russell, in the Province of Ontario, Canada,both subjects of the King of Great Britain, have invented certain newand useful Improvements in ater-Cranes; and we do hereby declare thatthe following is a full, clear, and exact description of the inven tion,such as will enable others skilled in the art to which it appertains tomake and use the same.

The invention to be hereinafter described relates to water cranes forsupplying the boilers of locomotives, and more particularly to thatclass of such cranes as are adapted to swing bodily about a pivotalsupport in order to allow the outer arm to be placed over the manhole ofthe tender to allow delivery of the water.

Broadly speaking, it comprises a suitable support, a crane pivotallymounted on the support, a sleeve or collar carried by the crane, alocking device carried by the crane and adapted to engage the cranesupport to lock the crane thereto, means carried by the crane forunlocking it, separate means carried by the sleeve or collar forunlocking the crane, valve actuating means carried by the crane forcontrolling the fiow of water to and from the crane, and means forlimiting the movement of the valve.

In order to more clearly disclose the construction, operation and use ofthe invention, reference should be had to the accompanying drawings,forming part of the present application.

Throughout the several views of the drawings, like reference charactersdesignate similar parts.

In the drawings: Figure 1. is a rear view of the crane; Fig. 2 is aview, showing in detail the relative positions of the crane and watermain in full lines; the valve operat ing mechanism being shown ininoperative position in dotted lines; Fig. 3 is a vertical sectionthrough the crane, showing the looking device in section, and one of themeans for unlocking the same; Fig. 4 is a front elevation of the lockingbolt, the collar and crane support being shown in section; Fig. 5 is asection on hne 9-9 of Flg. 2, lookmg in the direction of the arrow; Fig.6 1s a section on line 1010 of Fig. 2, looking in the direction of thearrow; and, Fig. 7 is a section on line 11-11 of Fig. 2, looking in thedirection of the, arrow.

A shell 1 of tubular form is made fast to a box or casing, in which areplaced the valve mechanisms for controlling the flow of water from themain to the crane. Through the shell is passed the upright branch 2 ofthe crane the lower end of the branch being removably and revolublyseated in a collar 3, which is detachably secured to a valve chamber at.This valve chamber is provided with a threaded boss 5, which screws intoa threaded seat in a block 6, and the block 6 in turn is provided with athreaded boss 7, by which it may be securely locked to the bottom of thecasing or box containing the valve mechanism. Thus the valve chamber,which may be easily inserted or removed, acts as a support for thecrane, which is free to rotate thereon, and the shell 1 acts as a guideand brace for the same.

hen it is desired to deliver water to a locomotive tender, the crane isswung so that its horizontal branch extends over the track. Of course,when not in use, the horizontalv branch should be held to one side ofthe track.

In order to prevent the accidental swinging of the horizontal arm intooperative position above the track, a locking device is provided. Thiscomprises a bolt 8, carried by a sliding rod 9, and adapted tosimultaneously engage a notch 10 in a flange on the vertical branch ofthe crane, and a similar notch 11 on a flange of the shell 1, beingpartly seated in each notch, and thus securely locking the revolublecrane to the stationary shell. The notches 10 and 11 are so placed as tolie in position to receive the bolt 8 only when the horizontal arm ofthe crane has been swung to inoperative position.

In order to enable the fireman to unlock the crane and swing it tooperative position wvithout dismounting from the tender, a rock shaft 12is journaled along the top of the horizontal arm of the crane, andprovided with wings 13, which may be readily engaged by an iron poker,or any other convenient tool. The free end of this shaft is providedwith a crank 14. A link 15 is pivoted to the upper end of the rod 9, andis provided with a slotted block 16, the crank 14 being slidably seatedin the slot thereof.

vided.

Thus, as the shaft 12 is rocked, the crank 14; will engage the uppersurface of the slot 17 and raise the link 15 and rod 9, withdrawing thebolt 8 from the notches 10 and 11, and unlocking the crane so that itmay be swung. However, should it be desired to unlock the crane from theground, a lever 1'8 is pro- This lever is pivoted between ears 19' on acollar 20, which is revolubly mounted on the'crane, and has a toe 21which engages under a lug 22 of the bolt 8, thus raising the bolt andfreeing the crane. The collar 20 is.

secured to the crane by means of set screws 23, which travel freely in agroove between fianges'2-ft and 25.

hen it is desired to use the lever 18, it is locked in inoperativepositionby means of the link 26, which passes through slots in the ears19, the slots being so placed that they will 'be between the toe 21 andthe lug 22 when the lever 18 is raised to inoperative position.Consequently, the link 26 will lie across the path of the toe and holdthe lever raised, all as clearly shown in Fig. 3. A screw or otherdevice 27is passed through one ear 19, in such position as to liebetween the opposite bars of the link and prevent it from fallingentirely out of the ear, and a small padlock 28 is adapted to engage theprojecting free end of the link when the link has been passed throughboth ears to hold the lever 18 raised.

When the crane has been swung to position for delivering water, thefireman grasps the elbow lever 29, which is pivoted to a bracket 30 onthe crane, and swings it tofull line position, as shown in Fig. 2. Byswinging the lever, the rod 31, pivoted to the elbow thereof, is pushedback, rocking the bell cranks 32, and forcing down therods 33. To therods 33 is secured a, collar 3%, which is loose to both slidelongitudinally of and rotate freely about the crane, and seated in thegroove in this collar in such manner as to allow the first collar torotate freely within it is a second collar 35, to which are connectedshort rods 36. The lower ends of these rods 36 are coupled to toggles37, which operate a swinging valve.

' In order to prevent rotation of the collar 35, and consequent twistingof the rods 36, a guide rod 41 is passed loosely through an opening inthe collar 35 and secured at its opposite ends to the base of the shell1, and to the exit pipe respectively. Thus, it will be seen thatalthough the collar 35 is free to travel longitudinally withthe collar34,

it cannot turn with said collar. -To prevent injury to the valveand'to-the valve seat of the main, when closing off the supply, a stopor limit device has been provided. This comprises a box 12 on each sideof the exit pipe, adapted to loosely receive and guide the free arms 43of the toggles 37. In the ends of these boxes are secured adjustingscrews tt. By ad ustmg these screws in or out of the boxes, they may bemade to.

engage the ends of the arms 43' at 'dilferent positions, and to thuslimit the upward movement or straining of the toggles. I By limiting theupward movement of the toggles, the closing or seating of the valve 38on the main for shutting off the water may be regulated as desired.

It is clear thatmany changes in the construction of the several parts.of the invention,amany substitutions for these parts, manyrearrangements of them and many other combinations may be had, withoutin any way departing from the field and scope of the invention, and itis meantto include all such within this application, wherein only onepreferred form of the improvement has been illustrated and described.

Having thus fully described our invention, what wev claim as new, anddesire to secure by Letters Patent, is

In a water crane, a tubular shell adapted to freely receive theupright branch of a crane, means for locking said upright branch andshell together, a collar slidably mounted on said upright branch, meansfor sliding said collar, rods connected to said collar, togglesconnected to said rods, and a feed valve connected to said toggles.
